Abstract

An apparatus and method is provided for interfacing a number of computer servers (or operating system domains) (302, 304, 306) to a network such as Ethernet (326) through a shared network interface controller (NIC) (320) which is part of the load-store architecture of the operating system domains. The network interface controller (320) includes a bus interface to couple the controller to a load-store domain bus (such as PCI-Express), the bus including header information to associate data on the bus with an originating operating system domain. The controller also includes transmit/receive logic to connect it to the network. In between the bus interface and the transmit-receive logic is buffering to temporarily store data coming either from the system domains or the network. The buffered data coming from the operating system domains or the network. The buffered data is tagged within an identifier., to associate it with one or more of the operating system domains. Association logic is further provided to allow the controller to designate, and later lookup which destination MAC address (on the ethernet side) is associated with which operating system domain. Control Status Registers (CSR's) specific to an operating system domain are duplicated and made available for each domain. Descriptor Register files are also duplicated for each operating system domain. A number of direct memory access (DMA) engines are provided to improve throughput. And, packet replication logic, along with filters (perfect and hash) and VLAN tables are used for looping back packets originating from one of the operating system domains to one or more of the operating systems domains, for server communication, multicast and broadcast operations.
